It will be apparent that the nuts 33 .and normally clamp the stop pins in their ad-kv justed positionl with relation to the vertical lane oftheV axis vof therespective buckets,

and that by loosening the nuts the pins may bemoved in the arcuate 'they extend for l" In the operation' of Vupper shaft being slowlyrotated' through the Vw ater above whir chainsand while Ward the water level 'slots through-which the purpose of changing their distance from said plane.

the water elevator, the

medium of the driving mechanism hereinbefore described, imparts its movement to thek sprocket `wheels from whichy the endless "chains are suspended.

' of airto be entrapped in the buckets with the `Vchains -to leaveV the result that they yremain inl an inverted posiy"tion while passing around Vthe sprocket wheels on `thek lower lshaft and are'gradually,

rotated on the upwardly moving side ofthe "water fin rtheir normal upright position. Y The watenwith which vthe buckets were filled during their passage through the vbody of waterfiscarriedoveixthe upper sprocket wheelsfand discharged yinto a chute38 at the downwardly vmoving side ofthe elevator.

By properv adjustment of the stop lpins' the movementof the 'buckets' about their pivotal Iaxes may be regulatedlso that the water is Y lifted with the minimum-expenditure of Ymotive energy and h their "different positions without violent impact with the chains on which-they are cari ried.

It will be observedthat the lowerfipair of '-sprocket wheels are not mounted' for rota- *tion about a fixed axis,

"tions of this type but act merely Vas a means 4to maintain the `chains. ina taut condition and l facilitate the `movement of Y,the buckets l through the body of'water to be lifted. i

Having thus described our-invention what weclaim and desire to secure' by Letters-Pat 1,. In a water elevator ofth'e character d'e-p scribed, the combination withan endless carrier. vand buckets pivotally mounted thereon,

of adjustable stop pins on the buckets, which scribed, the combination so that the buckets assumeV as in other construclimit the extent of their pivotal movementk f bv engagement with saidcarrier.

f N2. In a water elevator Yofthe character dc- Y scribed, the combinationwith an endlessV carrier and buckets pivotally ymounted thereon, of stop pins which limit the extentof the pivotal movement of thebuckets by engagement with the carrier, said pins being mounted at the ends of the buckets for adjustmentV to selected distances from'the vertical yplanes of the pivotal axes of thesamery f f Y i 3. In a water elevator of the character described, the combination with an endlessvcarrier, ofbucketspivotally ymounted thereon f and having at their ends slots concentric with their pivotal axes, and stop pins adjust- .ably fastened in.. said slots land adapted tov l i limit the extent of the-pivotal movement of y the buckets by engagementvwith the carrier. v
